Null-Valued Expression Error in Powershell - powershell

Question

I am trying to uninstall a Program via Power Shell but I am getting an error "You cannot call a method on a null valued expression.
PS C:\Users\user> $App = Get-WmiObject -Class Win32_Product | Where-Object{$_.Name -eq "CVF_x64"}
PS C:\Users\user> $App.Uninstall()
You cannot call a method on a null-valued expression.
At line:1 char:1
+ $App.Uninstall()
+ ~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: (:) [], RuntimeException

The program is in Programs and Features on control panel, see attached picture below.

CVF Doesn't show up in Powershell for some reason

Answer 1

looks like your query does not find anything -> empty variable?
$x = $null
$x.uninstall()
result: You cannot call a method on a null-valued expression.
btw. wmi is a thing of the past, use the cim cmdlets, and do the filtering one step earlier:
$name = "MyApp"
get-ciminstance -query "select * from win32_product where name = '$name'"
To identify what the value of the variable name must be simply output this beforehand and identify the exact string:
(get-ciminstance -query "select * from win32_product").name
You could also check the registry:
HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall
Get-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\*" -Name DisplayName,DisplayVersion,InstallSource,Publisher,UninstallString
Execute the command in the attribute UninStallString...
